BC mosquitoes: Scientist wants residents to send them in – Alaska Highway News

Published

 on


For most road-trippers, camping next to a swamp can be hell. 

Swarms of mosquitoes buzz in a shadowy path around your head. They alight on your ears, neck and back. And in the space of a few seconds, their serrated mandibles tear into your skin, opening a path for six-needled mouths to plunge toward their goal — your blood. Then comes the itching.  

But when dusk comes for Dan Peach, he’s the first to offer himself up as bait. 

Last summer, the mosquito researcher spent months hunting for the notorious insect near the province’s bogs, lakes and rivers. On mountain tops, he caught furry mosquitoes; in coastal estuaries, he stalked tide pool dwellers, which can survive and reproduce in water triple the salt content of the ocean.

In one recent trip to Whistler, Peach said he ducked under bridges “like a troll” looking for hiding mosquitoes.

It’s all part of an ambitious mapping project that aims to uncover the range of the 51 mosquito species already known to exist B.C.

From there, Peach will use the maps, combined with projected shifts in temperature and rainfall, to model how mosquitoes and the diseases they carry could spread on the back of a changing climate. 

“We think these things have already been heading further north,” said Peach. “As climate changes and some of these conditions shift, where will they be in the future?” 

But first, you need to catch them.

In his lab at the University of British Columbia, Peach pulls out an aspirator, what looks like an oversized turkey baster — only, instead of a bulb to suck in gravy drippings, he places the device to his lips and with a sharp inhalation, vacuums a mosquito into a filter inside.

Other mosquito-hunting devices are even less high-tech. To catch mosquito larvae he uses “a cup on a stick.”

“If they’re floating in the water swimming around and they see a shadow or something, they’ll dive down and hide,” he said. “So you get this cup on a stick and kind of lean in, like sneak up on them.”

At other times, the researcher will deploy a trap that looks like a foldable laundry basket with a lid and opening at the top. Black and white colouring attracts the insects, but so too does German-made synthetic sweat. 

Peach opens a cooler door to pull out a half-opened package filled with a handful of chemicals, each a key ingredient in reproducing “stinky person smell.”

“It just kind of smells like gym socks,” he says holding it up to this reporter’s nose.

In the field, German artificial sweat gets dropped in the trap with carbon dioxide, an irresistible mix as artificially human as Peach can achieve. 

But there are limits to what a single scientist — no matter how motivated — can do. In many small B.C. towns, you can’t find carbon dioxide. And no matter how much Peach travels across the region, he can’t be everywhere at once. 

Instead, Peach is hoping an army of citizen scientists will take up open palms to help him gauge the province’s ever-shifting mosquito population — one slap at a time.

“We’re calling it the ‘Ow! What just bit me?’ project,” said Peach, adding he also welcomes samples from Yukon. “Basically this summer, if you smack the mosquito, put it in an envelope and mail it to us.”

Add the date as well, plus the latitude and longitude of where it was killed (you can look that up on an application like Google Maps), he says. Once the lab receives the sample, they will grind it up and genetically sequence the remains to confirm the species. In return, Peach said he’ll email back information about what species of mosquito was slapped. 

More than a window into what bit you, a slap and a trip to the post office offer residents of B.C. and Yukon a hand in heading off future crises.

An unfathomable trail of bodies 

It’s hard to understate the risk mosquitoes pose to human health. By acting as a vector for everything from yellow and dengue fevers to malaria and Japanese encephalitis, the mosquito has killed humans at an almost unfathomable scale.

“Mosquitoes are the world’s deadliest animal,” said Peach.

Several researchers, including Peach, suspect malaria alone has killed half the people that have ever existed. Or as Bill Gates put it in 2014, mosquitoes kill more people than people.

(At the time, mosquito-borne illnesses killed an estimated 725,000 people per year compared to 425,000 people who died at the hands of other humans.)

Since then, Gates and others have poured vast sums of money into malaria control programs, reducing mortality from the virus by 36 per cent between 2010 and 2020. But by the end of the decade, an estimated 627,000 died still died from the disease. And at least 240 million more people are known to have suffered from the disease that year.

As one influential book on the deadly trail left by the insects put it, “The mosquito remains the destroyer of worlds and the preeminent and globally distinguished killer of humankind.”

“Mosquitoes had this very profound influence on humans,” said Peach. “And since humanity has been a thing, basically, and they continue to do so today.” 

“So there’s a very real risk here. And sort of because of that, we focus on that area, and we don’t really pay as much attention to the other things that mosquitoes do in an ecosystem.”

A dangerous vector heads north

Today, someone from Eastern Canada could be forgiven for thinking B.C.’s Lower Mainland has always been a mosquito-free haven.

“Sixty years ago, before they diked along the Fraser [River] and drained Sumas Lake, the Lower Mainland was considered worse than the Prairies by settlers who had come through,” said Peach.

As recently as the 1960s, the province suffered under outbreaks of mosquito-borne Western Equine encephalitis, and a century ago, the Interior had instances of malaria. 

“What’s here now hasn’t always been the case, and may not always be the case in the future. We need to kind of keep an eye on it,” said Peach.

One recent study, for example, found the Aedes aegypti mosquito could spread into some parts of British Columbia under several global warming emissions scenarios. The mosquito species is vector for a number of pathogens dangerous to humans, including chikungunya, dengue, Japanese encephalitis, zika, West Nile and yellow fever viruses.

Across the planet, there are more than 3,500 mosquito species. About 80 of those are found in Canada. But it’s not clear how the tiny creatures are moving. 

Of the more than 50 mosquito species in B.C., a handful are known to be invasive — including the Northern House Mosquito (Culex pipiens), which carries the West Nile virus, and the Japanese rock pool mosquito (Aedes japonicus), a species which has been in the province for about a decade.

Often a forest-dwelling day-biter, the rock pool mosquito is known to carry a number of diseases, including the West Nile virus and two forms of encephalitis — infections of the brain that starts with swelling and headaches and can lead to vomiting, seizures, and in some cases, death. 

But while B.C. is home to a number of mosquitoes known to spread disease, its climate is not yet ideal to allow some of the mosquito-borne vectors to follow. 

That could change in the coming years, as warmer summers and wetter winters expand the range of many species northward, even across oceans.

“In the last a few years, we’ve been seeing some of the West Nile vectors in places farther north than they were before,” Peach said. 

He points to Culex pipiens, which lately has turned up in Prince George.

“It was never thought to go that far north,” he said, noting the odd case in the southern Interior or Lower Mainland.

And while it’s likely too cold up there for West Nile to spread in the wild, there’s a risk an infected person could bring the virus with them in a bird-human-bird spreading event transmitted through the bites of the invasive Culex pipiens.

Mosquitoes are only one-half of the picture.

“Climate is definitely limiting the spread of these pathogens,” said Peach. “You need it to be warm enough for long enough for them to spread.”

“There might be areas when there’s nothing to worry about now, but perhaps, you know, 40 to 50 years in the future, we need to be concerned about pathogens like West Nile.”

A killer’s unsung role in sustaining life

Not all mosquitoes are pathogen-laden killing machines.

In fact, only female mosquito species take blood, and then only to develop their eggs. Many species don’t even target humans and only some carry pathogens that are dangerous to our health. 

Mosquitoes are drawn to flowers as much as people. Adult mosquitoes feed on plant sugar, bouncing from flower to flower like a bee, in a process that appears to have been playing out since at least the mid-Cretaceous period, over 100 million years ago.

In an odd adaptation, mosquitoes take advantage of ants and their habit of farming aphids to collect honeydew.

As Peach put it in a recent article: “When a mosquito inserts its mouthparts into an ant’s mouth and strokes the ant’s head with its antennae, it tricks the ant into regurgitating and sharing its honeydew.”

They also act as a massive food source, a link driving the transfer of energy from aquatic environments — where their larva filter microbes, alga and dead leaves out of the water — to insect tissue, a key food source for fish, bats, birds, frogs, spiders, and predatory insects like dragonflies and beetles.

Those mosquitoes that don’t get eaten, often fall to the ground, where their biomass enriches the soil. An individual mosquito won’t add much, but in Canada and Russia’s north, huge swarms have led some researchers to estimate half of all migratory birds would stop nesting if mosquitoes disappeared.

In Alaska alone, the biomass of mosquitoes has been calculated at over 43,500 tonnes — equivalent to 17 trillion mosquitoes.

In the Canadian Arctic, Peach says one researcher estimated how many bites he got on his arm in 10 minutes. Extrapolating out, he estimated standing naked among the Arctic mosquito swarm could leave a human dead from blood loss within two hours.

Closer to home, Peach says you’ll find huge swarms on British Columbia’s mountain slopes after a snow melt, or in valley bottoms after a flood. 

“Nobody can agree on [the numbers],” said Peach. “But it’s thought there are definitely more mosquitoes than there are stars in the sky.” 

However much you hate mosquitoes, the science is clear, says Peach. Humanity must find a way to strike a balance — target and control those that spread disease, but don’t kill what for many of the world’s animal and plant species forms a foundation for life. 


Anyone in British Columbia or Yukon interested in taking part in the citizen science ‘Ow! What just bit me?’ project is asked to:

  • Record the date you squished the mosquito;
  • Record the location using longitude and latitude (you can find this on apps like Google Maps on your phone or computer);
  • Include an email address if they want a response about what species they found;
  • Mail the information and mosquito to Dr. Dan Peach at:

Here is how to prepare your online accounts for when you die

Published

 on

 

LONDON (AP) — Most people have accumulated a pile of data — selfies, emails, videos and more — on their social media and digital accounts over their lifetimes. What happens to it when we die?

It’s wise to draft a will spelling out who inherits your physical assets after you’re gone, but don’t forget to take care of your digital estate too. Friends and family might treasure files and posts you’ve left behind, but they could get lost in digital purgatory after you pass away unless you take some simple steps.

Here’s how you can prepare your digital life for your survivors:

Apple

The iPhone maker lets you nominate a “ legacy contact ” who can access your Apple account’s data after you die. The company says it’s a secure way to give trusted people access to photos, files and messages. To set it up you’ll need an Apple device with a fairly recent operating system — iPhones and iPads need iOS or iPadOS 15.2 and MacBooks needs macOS Monterey 12.1.

For iPhones, go to settings, tap Sign-in & Security and then Legacy Contact. You can name one or more people, and they don’t need an Apple ID or device.

You’ll have to share an access key with your contact. It can be a digital version sent electronically, or you can print a copy or save it as a screenshot or PDF.

Take note that there are some types of files you won’t be able to pass on — including digital rights-protected music, movies and passwords stored in Apple’s password manager. Legacy contacts can only access a deceased user’s account for three years before Apple deletes the account.

Google

Google takes a different approach with its Inactive Account Manager, which allows you to share your data with someone if it notices that you’ve stopped using your account.

When setting it up, you need to decide how long Google should wait — from three to 18 months — before considering your account inactive. Once that time is up, Google can notify up to 10 people.

You can write a message informing them you’ve stopped using the account, and, optionally, include a link to download your data. You can choose what types of data they can access — including emails, photos, calendar entries and YouTube videos.

There’s also an option to automatically delete your account after three months of inactivity, so your contacts will have to download any data before that deadline.

Facebook and Instagram

Some social media platforms can preserve accounts for people who have died so that friends and family can honor their memories.

When users of Facebook or Instagram die, parent company Meta says it can memorialize the account if it gets a “valid request” from a friend or family member. Requests can be submitted through an online form.

The social media company strongly recommends Facebook users add a legacy contact to look after their memorial accounts. Legacy contacts can do things like respond to new friend requests and update pinned posts, but they can’t read private messages or remove or alter previous posts. You can only choose one person, who also has to have a Facebook account.

You can also ask Facebook or Instagram to delete a deceased user’s account if you’re a close family member or an executor. You’ll need to send in documents like a death certificate.

TikTok

The video-sharing platform says that if a user has died, people can submit a request to memorialize the account through the settings menu. Go to the Report a Problem section, then Account and profile, then Manage account, where you can report a deceased user.

Once an account has been memorialized, it will be labeled “Remembering.” No one will be able to log into the account, which prevents anyone from editing the profile or using the account to post new content or send messages.

X

It’s not possible to nominate a legacy contact on Elon Musk’s social media site. But family members or an authorized person can submit a request to deactivate a deceased user’s account.

Passwords

Besides the major online services, you’ll probably have dozens if not hundreds of other digital accounts that your survivors might need to access. You could just write all your login credentials down in a notebook and put it somewhere safe. But making a physical copy presents its own vulnerabilities. What if you lose track of it? What if someone finds it?

Instead, consider a password manager that has an emergency access feature. Password managers are digital vaults that you can use to store all your credentials. Some, like Keeper,Bitwarden and NordPass, allow users to nominate one or more trusted contacts who can access their keys in case of an emergency such as a death.

But there are a few catches: Those contacts also need to use the same password manager and you might have to pay for the service.

Pediatric group says doctors should regularly screen kids for reading difficulties

Published

 on

 

The Canadian Paediatric Society says doctors should regularly screen children for reading difficulties and dyslexia, calling low literacy a “serious public health concern” that can increase the risk of other problems including anxiety, low self-esteem and behavioural issues, with lifelong consequences.

New guidance issued Wednesday says family doctors, nurses, pediatricians and other medical professionals who care for school-aged kids are in a unique position to help struggling readers access educational and specialty supports, noting that identifying problems early couldhelp kids sooner — when it’s more effective — as well as reveal other possible learning or developmental issues.

The 10 recommendations include regular screening for kids aged four to seven, especially if they belong to groups at higher risk of low literacy, including newcomers to Canada, racialized Canadians and Indigenous Peoples. The society says this can be done in a two-to-three-minute office-based assessment.

Other tips encourage doctors to look for conditions often seen among poor readers such as attention-deficit hyperactivity disorder; to advocate for early literacy training for pediatric and family medicine residents; to liaise with schools on behalf of families seeking help; and to push provincial and territorial education ministries to integrate evidence-based phonics instruction into curriculums, starting in kindergarten.

Dr. Scott McLeod, one of the authors and chair of the society’s mental health and developmental disabilities committee, said a key goal is to catch kids who may be falling through the cracks and to better connect families to resources, including quicker targeted help from schools.

“Collaboration in this area is so key because we need to move away from the silos of: everything educational must exist within the educational portfolio,” McLeod said in an interview from Calgary, where he is a developmental pediatrician at Alberta Children’s Hospital.

“Reading, yes, it’s education, but it’s also health because we know that literacy impacts health. So I think that a statement like this opens the window to say: Yes, parents can come to their health-care provider to get advice, get recommendations, hopefully start a collaboration with school teachers.”

McLeod noted that pediatricians already look for signs of low literacy in young children by way of a commonly used tool known as the Rourke Baby Record, which offers a checklist of key topics, such as nutrition and developmental benchmarks, to cover in a well-child appointment.

But he said questions about reading could be “a standing item” in checkups and he hoped the society’s statement to medical professionals who care for children “enhances their confidence in being a strong advocate for the child” while spurring partnerships with others involved in a child’s life such as teachers and psychologists.

The guidance said pediatricians also play a key role in detecting and monitoring conditions that often coexist with difficulty reading such as attention-deficit hyperactivity disorder, but McLeod noted that getting such specific diagnoses typically involves a referral to a specialist, during which time a child continues to struggle.

He also acknowledged that some schools can be slow to act without a specific diagnosis from a specialist, and even then a child may end up on a wait list for school interventions.

“Evidence-based reading instruction shouldn’t have to wait for some of that access to specialized assessments to occur,” he said.

“My hope is that (by) having an existing statement or document written by the Canadian Paediatric Society … we’re able to skip a few steps or have some of the early interventions present,” he said.

McLeod added that obtaining specific assessments from medical specialists is “definitely beneficial and advantageous” to know where a child is at, “but having that sort of clear, thorough assessment shouldn’t be a barrier to intervention starting.”

McLeod said the society was partly spurred to act by 2022’s “Right to Read Inquiry Report” from the Ontario Human Rights Commission, which made 157 recommendations to address inequities related to reading instruction in that province.

He called the new guidelines “a big reminder” to pediatric providers, family doctors, school teachers and psychologists of the importance of literacy.

“Early identification of reading difficulty can truly change the trajectory of a child’s life.”
